Do they work with mountain bikes? As stupid as this sounds I like mountain biking but I don’t have stamina to climb up hills and then keep doing for a long time. I have an electric bike but designed for road
It says on the website it will fit hardtails but not full sus, and that it isn't recommended on knobby tyres due to performance which isn't ideal either.
I could be wrong on all of this but those are just the concerns coming to mind as another mountain biker.
I think the tyres would limit the power output most. Probably quite annoying to have no rear mudguard in anything but the driest conditions. You’d be spraying a lot of crap up at the motor (and probably your back).
Attaching and detaching it looks relatively simple, though - removing it for downhills doesn’t look arduous. You could probably 3d print a clip for the frame.
Given the likely reduced power, and that the spec seems to be saying ‘500w peak, but 250w is sensible’ - probably up to the user’s needs whether the hassle is worth the extra watts per kilo. For those without mobility issues or longterm injuries, it’s usually best to optimise the rider rather than the bike for that.
I feel like off-road climbing would necessitate really wide, sensitive speed variance that this motor is likely not great at supporting. It strikes me that you’d want more direct pedal feedback.
Really fun bike design problem.
Sorry but what? The only alternative to a FS frame is a hardtail. Where “hard” means that the rear wheel doesn’t move relative to the saddle. Your road bike is a hardtail.
If the rear wheel moves relative to the saddle, it’s full suspension (full meaning front and back)
The biggest issue to me is the inability to put the seat all the way down given that's quite important, and obviously this won't work at all with a dropper post (which are fairly common nowadays), honestly actual ebikes are quite popular in the mountain biking scene at the minute and they seem like a significantly better fit to me.
I wonder how much torque the motor could put out though without putting a lot of wear on your (probably fairly soft material on mtb) tyres or slipping on knobby, possibly dusty/muddy, tyres; that itself might kill it off for offroad climbing.
